Verdict - Reviewed

All five patches compile cleanly, pass `make check-mremapNN`
(checkpatch), and run to TPASS across multiple iterations. Each
conversion is traced against its original test's setup/algorithm/
oracle and preserves the full intent with no dropped scenarios, no
new leaks, and no double-unmap/double-free introduced.

The mremap04 Makefile switch from libltpipc to libltpnewipc was
verified against mremap06 and mremap07 in the same directory, neither
of which depends on the old ipc lib, so the switch does not affect
them.
